i)Based on Figure 2, explain how Bob can obtain and verify Kate’s public key.Provide step-by-step details of the key(s) and the type of primitive(s) that may be used to achieve this. iii) Suppose that Bob and Kate have distributed and verified each other’s public key. Bob wants to send a message to Kate such that only Kate can read it. Kate can also verify that the message is from Bob. Explain the steps that will be performed by Bob and Kate to ensure this. For this question, Bob and Kate are allowed to use only an asymmetric cipher.
Assume that passwords are selected from 8-character combinations of 26 alphabetic characters (every character can be in upper case or lower case and they will be considered different characters). Assume that an adversary is able to attempt passwords at a rate of two per second. a. Assuming no feedback to the adversary until each attempt has been completed, what is the expected time to discover the correct password? b. Assuming feedback to the adversary flagging an error as each incorrect character is entered, what is the expected time to discover the correct password?

What exactly is a Trojan horse? Here are three instances.
Describe a situation in which a user's complete denial of a service (i.e., the user gets no response from the computer) is a significant problem. Describe another case in which a 10% denial of service (i.e., the user's calculation proceeds at a 10% slower pace than normal) is a major problem. Is it possible that unauthorised access to a computer system will result in a ten percent service denial for legitimate users? How would you go about accomplishing that if that's the case?
Open with Google Docs Part V: From the material that we discussed about the public key certification, answ the following questions in details 1. The authentication that goes over the network must be done solely on the basis of messages and data exchanged as part of an authentication protocol. One authentication approach is to use an encrypted secret key password. a. Explain why that the communication with this authentication is not fully safe. b. Explain in details the solution suggested for this, i.e., discuss the improved authentication approach. 2. Explain why that the trust is necessary in issuing certificate authority.
Let's pretend that Alice and Bob are exchanging data packets across a network.Let's say Trudy infiltrates the network and is able to read all of Alice's data, then forwards it on to Bob along with whatever other information she chooses. Provide some examples of what kind of harm Trudy can do from this vantage point.
Question Suppose that users Alice and Bob carry out the 3- pass Diffie-Hellman protocol with p = 101. Suppose that Alice chooses a1 = 19 and Bob chooses b1 = 13. If Alice wants to send the secret message m=5 to Bob, show all the messages exchanged between Alice and Bob
Consider Diffie-Hellman Key Exchange protocol between two users Alice and Bob. Let prime number q = 13 and primitive root a= 2. They are public known. Suppose Alice generates private key XA = 4 and Bob generates private key XB = 5. 1. What is Alice's public key sent to Bob? 2. What is Bob's public key sent to Alice? 3. What is the common shared secret key established by Alice and Bob?
